This is a list of all the usergroups members can join and what their entry requirements are. Generally, these rules are not negotiable.

Brotherhood of the Monkey: Send a private message to one of the group moderators expressing your interest. Applicants must have a minimum of 500 posts, have been on the board 3 months and be 18 or over.

Heavy Armor Brigade: 200 posts minimum and a requirement for the person to have a demonstrated interest in military history and technology. That can come either from posts they've made, or questioning by The Great Leader. Contact: Sea Skimmer

The Mess: Must be a current or former member of the armed forces. Prospective members will be invited to join if they can prove their military experience (The "Challenge of Doom"). Additionally, prospective members should be an active member of the board in good standing for at least three months. Contacts: Rob Wilson, Coyote, RogueIce (Temporary group moderator)

SoS:NBA: Society of Sisters (No Boys Allowed). Applicants for the SoS:NBA must have at least 100 posts and have been a member of the board in good standing for at least three months before access to the forum will be considered. No exceptions will be made. (Obviously, applicants must be female (the group welcomes transwomen too) as well) Contacts: Broomstick, Cairber

GALE Force: The applicant must be gay, lesbian, bisexual, transgendered, or curious/confused. The applicant must also have been a member of StarDestroyer.Net for at least a month with a post count of at least 100; a SDN member in good standing vouching for a prospective GALE Force member can make that requirement redundant, however. Contact: Frank Hipper

Mecha Maniacs: Interest in scifi/anime technology, usually but not entirely limited to walker-style machines; must have spent at least 3 months on the board and must not have earned a derogative title (Village Idiot, for example). The moderator's gut feelings on a person might lead him to accept them earlier or not accept them later, though. Contact: Kuja

Justice League: Comic books fan group. Must have around 100 posts and have been a member for three months. Must have a relevant interest in comics. Contact: Steve

Nitram, slightly high on cough syrup: Do you know you're beautiful?
Me: Nope, that's why I have you around to tell me.
Nitram: You -are- beautiful. Anyone tries to tell you otherwise kill them."A life is like a garden. Perfect moments can be had, but not preserved, except in memory. LLAP" -- Leonard Nimoy, last Tweet
